Heather took a few deep breaths to calm herself. This was going to be difficult, she just knew it. A few times before she had had to pee in less than usual circumstances and it had always been difficult. That time in the portapotty was understandable, it would have been difficult for anyone having some drunk guy pounding on the door the whole time. And that time she had to go in the bushes while camping had actually been painful. She had managed it both times, but only just. To her shock this wasn't like that at all.
Her bladder released quite readily, allowing a stream of warm urine to splash into the thirsty padding between her thighs. Heather gasped at the sensation. This was heaven. She leaned back and spread her legs as the wet heat spread from the front to the back of her diaper. Closing her eyes she allowed herself to bask in the feelings of utter freedom and joy that flooded her body as she flooded her diaper. After what felt like hours, but was surely only moments, she allowed herself to come down from the high. The warm feelings had spread out from her crotch and she could feel it in her legs. Hold on... That wasn't right...
Heather looked down at her soaked diaper in horror. Though the diaper did fit, technically, it had to stretch a bit and the tapes only barely made it around her waist and hips. The diaper was made for a very small child, not a teen, it couldn't hold the entire contents of her full bladder. She was sitting in a rapidly cooling puddle that was quickly soaking into the carpet of her bedroom.
In a panic Heather jumped up and ran to get some towels. The cleanup was no where near as enjoyable as the wetting had been. About an hour later she tossed the sodden towels into the wash. She had been able to soak up the pee, but she swore there was a faint yellow tinge to the spot now and there was certainly a faint odor. Her mother had some special cleaner for this sort of thing and she had used it liberally. It must be her imagination.
Worn out from her brief high and the frantic, panicky cleanup afterwards Heather made her way into the bathroom for a shower. As she entered her gaze was caught by the figure in the mirror. She was still wearing the diaper. She had completely forgotten about it in her rush to clean. The padding was definitely yellowed and she could clearly see the marks left from multiple streams of urine that had dried on her legs. With a sigh she reached down and pulled the tapes free. The diaper fell to the tiled floor with a heavy, wet splat. Heather left it lying there, struggled out of her tight top, and stepped into the shower.
After a thorough scrubbing Heather took the heavily used diaper and stashed it in diaper pail in her brother's nursery, hiding it under some other used diapers just in case. She looked over at the changing table and sighed. These diapers just wouldn't work. They were too small and if she kept taking them then her mother was sure to notice. Returning to her own room she got dressed. Sweats, a regular t-shirt, and panties. The panties didn't feel the same anymore. They felt thin and fragile despite their thick woven cotton. She needed another diaper, and soon.
Sitting on her bed, she considered her options. She knew they made diapers for adults, she had seen them before in commercials. She thought about where she could get them. The grocery store might work, she was certain she had seen some next to the pads and other feminine hygiene products. The drug store was another option and would probably have a larger selection to choose from. And there was always the internet, though she wasn't sure she was willing to wait for shipping and there was a risk of any packages being intercepted by nosy parents. What should she try?
